Fer-tented May, 1 1, 1809.

To all whom it may concern:

Be it known that we, DALTON K. WILsON and ARTHUR W. LEE, citizens of the United States of America, and residents of Waterloo, 5 Blackhawk county, Iowa, have invented certain new and useful Improvements in Manure-Spreaders, of which the following is a specificat1on.

Our inventionrelates to improvements in manure Spreaders, and the objects of our improvements are these: first, to rovide an improved awland ratchet riving mechanism or the -mova ble conveyer-apron, adapted to be adjusted to vary the speed; of such apron {and second, to furnish adjustable means for connecting and disconnecting the rotatable distributing-drum from the source of power adapted to actuate it. Thes ob'- ects we have accomplished by the mee hanism which is hereinafter fully described and claimed, and which is illustrated ifidhe accom' anying drawings, in

Flgure 1 is an elevation t me right-hand side of a wagon-box equipped with our improved pawl and ratchet driving mechanism, and with our improved. adjustable.

connectingand disconnecting device; Fig. 2

is an elevation of the left-hand .of said disconnecting is a plan of the upper face of the media pivoted driving-lever for the ratchet-wheel, and Fig, 4 is an enlarged u per plan view of the details of the sliding-bl d'ck and slideway of ,said adjustable connecting and disconnectin device.

throughout the several views.

' The wagon-box 40 contains a movable conveyor-apron 48, which has its side-chains driven by sprocket-Wheels 63 on the transverse shaft 22 which is driven b the ratchetwheel 21 on the right-hand si e of the box. A distributin -drum 1 is mounted on a transverse rotatab e shaft 2, theends of the latter resting in bearings in rearwardl -extending brackets 8, the latter secured to the deliveryends of the side-boards of the box. 40 by bolts 61. Secured to the right-hand end of the'shaft 2 is a cam-wheel 6, and a driven sprocket wheel 5 is secured to each end of the samev shaft. I

On each'side of the wagon-box are secured y w the parallel horizontal uide-bars 28, secured by bolts 23 and 27, an provided with longiwagon-box showing the similar? connecting, an evice'for that side; 3'

f I means of any suitable source of -S1m ar numbers refer to similar parts box ongitudinally, may be secured to said so guide-bars. The plate 26 is longitudinally slotted to form parallel bars, the latter acting as slideways for a slide 32, the latter being vertically grooved along the sides to hold it from becoming detached, but other securing means may be used if desired. The slide 32 has a downwardly-extendin arm 34, provided near its lower end wit a plurality of orifices 35, in one of which a intle 36 extending from the 'arm 37 may e mounted. 7c The arm 37 is secured to the end of a transverse rock-shaft '38 under the wagonbox mounted in hanger-bearings 39, said rockshaft thus being secured to an arm 37 on side. Each slide 32 is adapted to move up or down within the ways in said lates 26. Each-slide 32 has a transverse orlficed seat for a transverse horizontally 'slidable shaft v33, each shaft being adjustably secured in its seat by a set-screw 31. On one end of each shaft 33 arespaced collars' 59 and 60, be-

tween which an idlers rocket-wheel29 is rotatably mounted on t e shaft. A sprocket chain 30 on each side of the box connects the idler 29 and the driven sprocket-wheel 5 on the distributing-drum shaft 2.

then the sprocket-chains 30 on each side are simultaneouslylowered with the slides 32, they enga e theteetli of sprocket-wheels 62 on each si e, the latter bemg rotated by oWer. When the chains 30 are elevated wit said sl' they are disconnected from said drivingg hqockehwhe'els, and the rotation of the r uting-drum i1 is stop ed. Another 90 arm 57 is secured to the leftand end of the rock-shaft 38, and a connecting-rod 54 is pivoted to said arm 57 and to a hand-lever43 which is pivoted at 55 to said box 40, and which works within a rack-bar 50 secured to said box b bolts 49 and 51, the rack-bar having ori ces 52 to receive detachable securing meansfrom said lever. The moving back and forth of said hand-lever causes the elevation or lowering of the chains 30 simultaneousl Thea 'ustabilit of the slide-plate'26 longitudinal y along t e brackets 28 permits the taking up of any slackness in the chain 30.

The adjustability of the connection between 58 are rotatable inthe bifurcations of the lever. The rear end of this lever is so lo,- cated that its anti-friction roller 3 contacts with the edge of'the cam-wheel 6, whereby said' cam-Wheel causes a reciprocation of the lever when the shaft 2 is set in rotation by the mechanism hereinbefore described. A pulling-pawl 20 has its intles 16 pivoted in bearings in the bifurcate forward end of the lever 7, said awl engaging and being adapted to rotate t e ratchet-wheel 21 when the said lever is reciprocated. A holding-(pawl 4 is medially-pivoted on the same fixe stud 13 as is the lever 7, and has its holding-end in engagement with the ratchetwheel teeth, while its forward prolongation 14 is connected at 17 to a tension-spring 19 whose other end is connected at 18 to the pulling-pawl 20. This resilient-connection etween said pawls not only tends to keep the awls in contact with the ratchet-wheel to click back thereover, but also aids in keeping the roller 3 in contact with the camwheel, and in balancing the lever 7.

A hand-lever 44 is pivoted to the box 40 "at 47, and works in a rack-bar secured to said box by bolts 41 and 45' The rack-bar has holes 42 to receive detachable engaging means on the lever to permit of its adjustment therealon A connecting-rod 15 is swiveled to the ever 44 at 46, a In 11 being located on the rear portion of sai rod, also a slide 12, and a spring 10 between said lug and slide, which thus furnishes a resilient contact-piece between said rod and an n right arm 9 on the lever 7, the rear end of t e rod passin slidably throu h an orifice in said arm. en the han -l-ever 44 is shifted it causes this resilient-connection to press against the arm 9, and force the said connection to lie at a certain location within,

the path of travel of said arm, which varies the stroke of the lever and pawl 20, and thus varies the s eed of the apron 48 by the action on the rate et-wheel 21. The resilient-conliection prevents shock and breakage of arts when the shifting of the lever 44 is sud enly efiected, by the ielding of the s ring 11 which gives enoug to allow for the inertia of the arts to be adjusted.

'aving described our invention, what we claim as new, and desire. to secure by Letters Patent, is: I
